Genes affected

HTR1A (HGNC:5286): (5-hydroxytryptamine receptor 1A) This gene encodes a G protein-coupled receptor for 5-hydroxytryptamine (serotonin), and belongs to the 5-hydroxytryptamine receptor subfamily. Serotonin has been implicated in a number of physiologic processes and pathologic conditions. Inactivation of this gene in mice results in behavior consistent with an increased anxiety and stress response. Mutation in the promoter of this gene has been associated with menstrual cycle-dependent periodic fevers. [provided by RefSeq, Jun 2012]

HTR1A Gene-Disease associations (from GenCC):

• menstrual cycle-dependent periodic fever
